Last time we found Lengths and Centroids. Today we are finding Area of Surface of Revolution. Formula for Area of Surface : 1: Revolution about x-axis ( y >= 0 ) Surface area= Int. from a to b of 2pi y((dx/dt)² + (dy/dt)²)^(1/2) dt (1) 2: Revolution about y-axis ( x >=...

In my work as a data scientist, I’ve come across various statistical tests, but one that stands out for its versatility in non-parametric scenarios is the Friedman test. This non-parametric test is a reliable alternative when dealing with paired samples or repeated measures that don’t me...
